Uveitis, Optical Coherence Tomography
Brief summary
Optical Coherence Tomography (OCT) is routinely used in ophthalmic clinical practice. It uses infrared light to image patient's eyes. Some patients, such as those with an inflammatory disease called uveitis or those who have just undergone cataract surgery, have intraocular inflammation. This intraocular inflammation commonly manifests as cells that can be seen on routine microscopic clinical examination. However, the only currently available method to quantify this intraocular inflammation is by manually counting on the microscopic clinical examination. The investigators plan to use the OCT machine to image patient's eyes. The investigators will then use the images obtained from the OCT to objectively quantify the degree of intraocular inflammation.
Interventions
The OCT scan is a brief, non-contact scan of the back of the eye using infrared light. Subjects will see a light and be asked to look forwards while the scan is completed.
This is a brief, non-contact ocular exam.

| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Identified Inflammatory Cells on OCT Scan | Through study completion, up to 1 year. | This measure pertains to the identification of cells in OCT scan of the participants. The inflammatory cells to be identified refer to white blood cells. The anterior segment OCT scan was used to attempt to identify these cells in the anterior chamber of the eyes of the participants. |
